"WebCapillary drying is based on capillary action and surface tension to expel the H2 O. Individual wafers in a plastic holder are slowly pulled out of DI H 2 O at 80–85°C into a controlled atmosphere. Less than 1 wt% of the H 2 O is claimed to evaporate, leaving a particle-free surface [176]. " - Capillary drying

Capillary water is water held in capillaries (soil pores). Like these other older, qualitative terms, it is not a precise concept. Think of it as any soil water present when the soil is not air-dry.

WebCapillary effects in porous media are directly linked to the wetting of an initially dry porous medium by a fluid phase. Wetting is the ability of a liquid to stay in contact with a solid due to intermolecular interactions, creating a balance between adhesive and cohesive forces. WebCapillary action is the basis for thin layer chromatography, a laboratory technique commonly used to separate small quantities of mixtures. You depend on a constant supply of tears to keep your eyes lubricated and on capillary action to pump tear fluid away.
